Abstract
There is provided a method of controlling circuit breakers in a multi-phase power system. The method includes (a) recognizing a concurrent presence of a first fault in a first phase of the power system and a second fault in a second phase of the power system, where the power system includes a first circuit breaker situated to conduct a fault current between the first and second phases, (b) controlling a second circuit breaker to open so that the fault current is interrupted, where the second circuit breaker, when closed, provides current to the first circuit breaker, and (c) controlling the first circuit breaker to remain closed until the second circuit breaker is opened.
